Regions

South Coast, Powell River, North Shore, Tetrahedron.

Avalanche hazard will be elevated throughout the day on Saturday with strong winds and heavy snowfall.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported.

If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network

Snowpack Summary

Incoming snow will bury a widespread melt-freeze crust at all elevations with up to 30 cm by the end of the day Saturday. The crust should continue to bridge any previous layers of concern deeper in the snowpack.

Weather Summary

Friday Night

Mostly clear with no precipitation, south alpine winds 10 to 30 km/h, treeline temperature -6 °C.

Saturday

Cloudy with 10 to 30 cm of snow, south alpine winds 50 to 70 km/h, treeline temperature -6 °C.

Sunday

Cloudy with 10 to 20 cm of snow and chance of rain at lower elevations, southwest alpine winds 40 to 60 km/h, treeline temperature 0 °C.

Monday

Mostly clear with no precipitation, south alpine winds 10 to 30 km/h, treeline temperature 0 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Closely monitor how the new snow is bonding to the crust.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
